Is your feature request related to a problem? Please describe.

• Follow-up to https://github.com/nextcloud/notifications/pull/1974
  • Since notifications app code is duplicated to talk-desktop client, we need to get this feature in as well

Describe the solution you'd like

• Desktop => Notifications: add support of second ringtone playing (see original PR)
• Talk => Settings: allow to pass custom settings sections to Talk Settings Dialog

Describe alternatives you've considered
